Jam the hell out of cell phones as it combats the communication of gang leaders who still control operations on the streets.

Let me clarify. It's not too difficult to jam a GSM network, if you find out the paging signal, you can jam that and prevent a cell from seeing the site to make a call.
CDMA is a different animal. It's developmed from frequency hopping technology pioneered in WW2 that was designed to circumvent enemy jamming techniques. CDMA is difficult to jam because those six CDMA bands that the FCC licenses out is between 25 and 60 MHz wide and that signal uses all of that single band to transmit. To jam a CDMA signal, you'd have to jam the entire band that it operates on.
With that said, I have to question the effectiveness of any broadband jammer (especially the portable unit ASU2003 showed me) to effectively interfere with a CDMA signal (such effectiveness at preventing an IED from being triggered has already been called into question by some in the defense field). As a jammer's bandwidth increases, it's effective power decreases without significant amplification. If a signal is too powerful, rest assured it's mucking up other forms of wireless communication through the introduction of excessive noise.
I'lll give a better explaination tomorrow, because I'm dead tired.
